    Coefficient Bounds for a Certain Family of Biunivalent Functions Defined by Gegenbauer Polynomials by Isra Al-Shbeil, Abbas Kareem Wanas, Abdelkader Benali, Adriana Cătaş

    Published 2022-01-01
    “…In the present work, by making use of Gegenbauer polynomials, we introduce and study a certain family of λ-pseudo bistarlike and λ-pseudo biconvex functions with respect to symmetrical points defined in the open unit disk. We obtain estimates for initial coefficients and solve the Fekete–Szego¨ problem for functions that belong to this family. …”

    Multibit image watermarking algorithm resistant to geometric attacks based on level set method

    Published 2011-01-01
    “…A multibit watermarking algorithm based on level set method was proposed.First,the stable location of the unit disk was found using level set method.Then,pseudo-Zernike moments were calculated.At last,the watermark was embedded by modifying the pseudo-Zernike moments.In the extraction process,the root-mean-square-error method was employed to detect the watermark.Simulation results show that the algorithm overcomes the defect of the traditional al-gorithm based on pseudo-Zernike moments,while be robust against geometric attacks.…”
